HOSE-COUPLING.

Application filed August 4,

T 0 all. whom it may concern;

Be it known that I, ROBERT M. DIXON, a cltizen of the United States, residing at East Orange, county of Essex, and State of New Jersey, have invented certain new and useful Im rovements in Hose-Couplings, 'of

which t e following is a specification,

My invention relates to a new and imrovedcoupling for steam hose in car heating.

n the accompanying drawing, I have shown a ,construction in which one form of my invention is embodied, the same being that form of my invention which I at present consider the best embodiment, it being understood, however, that this form is illustrative merely and that I do not limit my invention thereto but desire to include within myclaims any analogous structures which may be justithe state of the art and it is with this understanding that I desire my claims construed'.

In the drawing, Figure I is a side elevation of one member of a hose coupling in which my invention is embodied, it being understood that I preferably employ two similar members to constitute the coupling; Fig. II is a face 'or end view of the coupling member; and Fig. III is a'longitudinal vertical section on line III-III of Fig. II.

The main object of my invention is to produce a coupling in which the compressions of strain are received by springs under compression so as to compensate for wear and other pressure. over the faces of t e gaskets thus diflerentiating from a single spring around the shank of the coupling.

In the embodiment of my invention shown in the drawing, I have shown a plurality of springs arranged so as to bring an even pressure. between the bearing surfaces of the gaskets. Two springs on opposite sides are shown.- Three springs might be used in which case-they .should be spaced at angles of 120 degrees'wi'th each other.

For the purposes of this specification, it may be assumed that the plane indicated by the section lineIII-III'in Fig. II is the plane of hang of the coupling and train pipe.

Referring now to the drawing, 0. indicates anyordinary tubular portion of the coupling member adapted to be secured to the flexible train pipe. I have shown a sleeve 1) I screw-threaded therein and preferably held in nlace bv a screw 0 or other securing means. '2

1904. Serial No. 219,496. I

This sleeve 1) constitutes the body of the coupling and is recessed at its front portion to receive a gasket and its securing means. In the present instance, Lha've shown this sleeve or body portion as provided with an annular recess d with a shouldered portion e and a recess f.

The gasket 9 rests against the face of the coupler head and is contained within the recess f bearing against the inclined face 6 of the shouldered portion e. The shouldered portion is herein shown as of annular form. The gasket g is herein shown as a composition gasket molded upon a sheet metal ring h recessed at i for the reception of a locking member herein shown as an annular spring j having its ends is protruding inwardly through the slotted portion l of the sheet metalring h. The front face of the coupler body is preferably scored as at m to afford a better grip on the gasket, which gasket is also preferably provided with a wear ring or plate 0 scored internally and embedded in the gasket.

A movable sleeve 1) surrounds the coupler body I) and is recessed at q and 1' for' the reception of springs s and t. The sleeve p is freely movable on the body I) of the coupler member, which body portion is provided with lugs 11, against which the springs s and t bear. These springs s and t are located along the line IIIIII and when the coupler is in its normal position, will exert their pressure evenly to push the gasket faces together.

By thus constructing the coupling, I am enabled to effect the act of coupling by swinging the coupler members in a vertical plane as has been heretofore practiced on railroads.

For the purpose members together, coupler member with com lemental locking means. One member of t is'locking means comprises a side arm '0 having a curve hook-shaped face w notched at 00 to receive the point y of a side lug or bead z of the complemental coupler member. This side lug z is rovided with a curved edge 1 undercut as inc icated at 2 to cooperate with the undercut portion of the hook-shaped edge w.

It will be obvious that when the coupler members are brought together in the ordinary act of coupling, the cam surfaces w and 1 will cause compression of the springs s an t and the gaskets will be held firmly face to of locking the coupler I have provided each face, the sprin s takin up the shrinkage due to Wear of gas ets an other causes and the coupler members being firmly locked together by the engagement of the lug or bead and a spring controlled sliding connecting device having complemental engaging means for engaging another coupling, the said s ring controlled sliding connecting device eing comprised 'in part by independent springs arranged. u on diametrically opposite sides of the coup ing body and lying in a plane at right angles to the plane in Which lie the complemental engaging means.

2. In a hose coupling, in combination, a con ler body, a member thereon provided Wit complementary engaging means, .and

springs combined With said member, said springs being arranged in a plane at rightangles to the plane .of said engaging means.

3. In a gravity hose coupling, 1n combination, a coupler-body, and a spring-controlled member provided With complementary engaging devices adapted to slide thereon, the

springs thereof being arranged in a single diametrical plane and in the-plane of the hang of said coupling.

4:. In a hose coupling, in combination, a

coupler body, a movable connecting member thereon having a lurality of springs arranged in one diametrica plane, and complementary engaging means arranged in a plane at rightangles thereto.

5.. In 'a device of the class uesoribed, in combination, a coupler body, a connecting member provided with complementary engaging means arranged in a-hori-zontal plane and a plurality of resilient means operating upon said connecting member, said resilient means being arranged in'a vertical plane. v 6. In a hose coupling, in combination, a flanged coupler member, a sleeve slidably mounted thereon having a locking arm on one side and a locking projection on its opposite side adapted to engage and couple with similar locking devices upon the reciprocal coupler member by a downward swinglng movement, and a pair of springs interposed between the flange of said coupler member and said sleeve, said springs bemg arranged upon opposite sides of said coupler member and located in a lane at right angles to the plane of saidlocl ing arm and projection.
